Can you eat leftover fish while pregnant?
Check firstYes, leftover fish is safe when it was chilled quickly and reheated until steaming hot, to 165°F. Eat it within three to four days of cooking, and throw it out if it sat at room temperature for more than two hours.
Why
Cooked fish is a ready-to-eat food once it cools, and Listeria is the one bacterium that keeps multiplying at refrigerator temperatures, which is why the CDC tells pregnant readers to reheat leftovers until steaming hot rather than eating them cold from the fridge. FoodSafety.gov sets that reheating target at 165°F throughout, the same temperature used for any leftover. The fish itself is not the problem: a salmon fillet you cooked last night is fine, a cold piece of it eaten straight out of a container that has been open for five days is the risk.
Safer alternatives
- Freshly cooked salmon or cod reheated to 165°F in a skillet or oven
- Canned light tuna or canned salmon for a cold salad
- Shelf-stable pouches of cooked tuna opened the same day
- Hot-smoked salmon heated until steaming for pasta or eggs

Frequently asked questions
How long is leftover cooked fish good for in the fridge?
Three to four days, kept at 40°F or below in a covered container. Get it into the fridge within two hours of cooking, since Listeria and other bacteria grow fastest while the food is cooling on the counter. If you are not sure when you cooked it, throw it out.
Can I eat leftover fish cold, like in a salad or a sandwich?
It is safer to reheat it to steaming hot first. The CDC advice for pregnancy is to heat refrigerated leftovers through rather than eating them cold, because chilling does not stop Listeria from multiplying. Reheat the fish, let it cool for a few minutes, then flake it into your salad.
Is restaurant leftover fish I took home safe to eat the next day?
Only if it went into the fridge within two hours of being served. A takeaway box that rode around in a warm car or sat out through the evening has spent too long in the temperature range where bacteria multiply. If it was refrigerated promptly, reheat it to 165°F and eat it within three days.
